Journal of the ACM}


\opening{Dear Prof. Vianu}
I am herewith submitting our paper (co-authored with Atish {Das Sarma}, Gopal Pandurangan and Prasad Tetali) titled ``Distributed Random Walks" for review at Journal of the ACM. The paper deals with the fundamental problem of computing random walks on distributed networks.
%
It presents a sublinear time distributed algorithm for  performing random walks and its applications.
%It improves upon previous algorithms and also present the first-known non-trivial lower bound.
%
%The main technical ingredient of our algorithm is a ....
%This can also be of independent interest.

Preliminary versions of this paper appeared in the ACM PODC 2009 and 2010 conferences. The submitted version is a unified and enhanced version of the two conference
papers. In particular, the ideas developed in both papers are presented under the unified view, many missing proofs have been added and many details
regarding the model etc. have been clarified. The presentation has also been improved.

We would like to suggest Prof. Eli Upfal as an editor to handle the paper.

We request your help in  speeding up the review process and would be happy
to help in any way we can.

Thank you very much. We appreciate your help.

\closing{Best regards,}
